' Machines, of which the following is a speciication.

The invention relates particularly to that class ot ironing machines which include aheated curved metallic shoe which co-opcrates with a rotating cylinder. ln such a machine the roll is generally covered with a soft layer of felt or other similar material over which may loe placed a sheet ot cloth. llt is customaryl in such machines to provide mechanism for forcing together the shoe and roll and for separating them. A motor or other suitable mechanism is provided for rotating the roll and in some cases mechanism is provided for freeing the roll ltrom. the motor so that the roll may be stopped from rotation without stopping the motor. ln order to work satisfactorily it has been found necessary or desirable to insert a spring in the mechanism which holds the Shoe and roll together in such a way that it will he capable ot allowing some reliet when materials of varying thickness are passed between the roll and shoe in the rocess orD ironing. Associated with the ro and shoe is generally a feeding table trom which the clothes to he ironed may be ted tothe roll. ln the preferred form et the present invention this table is normally 'horizontal and admits ot a very slight tilting motion under pressure. Yll'he arrangement may be such that the tilting 'movement may eect a separation ot the roll and shoe.

ln the accompanying drawings is shown an embodiment oil the invention. Figure "i is an end elevation ot the ironing machine., Fig. 2 is a longitudinal horizontal section through the shoe. Fig. 3 is a plan view ot a portion or the machine showing the mechanism lor operating a clutch which controls the rotation ot the roll. Fig. l is an end view ot the A.tragment shown in Fig. 3. Fig. 5 is a partial iront elevation ot the machine. Fig. 6 is a. horizontal transverse section of a part of the fragment shown in Fig. 5.

The shoe 1 is stationary and the roll 2 is moved toward or from it. The bearing 22 tor the roll 2 has projecting from it a lug 3 which is exteriorally threaded to receive 1921. Serial lilo. 474,502.

a coil spring The lug 3 has an interior cavity to receive the end of an eye bolt 5'. on which is threaded a plug 6 upon the outer surface of which may be screwed 60 the other end ofthe spring 4:. The frame 7 of the machine has a pin 8 below the eye bolt 5. Mounted on the pin 8 is a lever arm 9 pivoted at its upper end to the eye bolt 5. Another pin 10 on the forward end 65 of the frame 7 carries a pivotal segment 11, a projection from which is pivoted at 12 to a link 13 the other end of which engages the eye bolt 5 and the lever arm 9. From the forward end of thef'zarc 11 depends an oper- 70 ating rod 14 which may be operated by any well known means such as the usual pedal (not shown). lt will be seen that a downward pull on the rod 1a will cause the eye bolt 5 to contract the spring t and force the 75 roll 2 against the shoe 1. The pin 12 never rises to the height of the two opposite pivots 5 and 10 of the toggle so that the toggle will not stay extended'to hold the roll and Shoe in contact. causes the pivot pin 12 to rise. rll`he pivot pin 12 extends outwardly from the arc into position to be engaged when in its uppermost position by a depending hook 15 pivoted at 16 on the frame 7. The hook 15 has 85 a. forwardly extending arm 17 in which is set an adjustable set screw 18. "llhe usual feeding board 19 for the ironing machine is pivoted about 16 and is-supported by a spring 20 in a substantially horizontal posi- 90 press the arm 1T and so cause the hook 15 to 95 release the pin 12 and allow the roll and shoe to separate. A projection 21 on the hook 15 keeps the pin 12 from rising to the dead center of the toggle so that when released hy the hook the pin 12 will fall and 100 the roll and shoe will be separated. yl'his apparatus may be at one end of the machine only or at both ends.

ln Figs. 3. 4 and 5 are shown the arrangement provided at the right hand end ot' the MD5 machine for rotating the roll. This apparatus may be duplicated at the lett hand ot the roll or might be there alone. Mounted in the frame 7 is the shaft 34 on whichthe roll 2 is rigidly mounted. A clutch member 1ro having a key way sliding on a hey 5a on the shaft 34 has a collar 36 by which it may 'lhe movement of the toggle @il be shifted longitudinally on the shaft 34. Carrying aco-operating clutch is a gear 37 loose on the shaft 34. The gear 37 engages a pinion 38 carried by a Worm Wheel 39 which engages a Worm 40 suitably supported on the vframe 7. Adjacent the shaft34 is a lug let in the frame carrying a pin '45 to which is fastened one end of a coil spring 46. The other end of the coil spring 46 engages a lever -l9 pivoted on the pin 45. One end 4T of the lever 49 engages the collar 36 of the clutch member and the other end 48 of the lever 49 normally engages a lug 5l carried by the frame. proaches the shoe the clutch is released to cause the roll to rotate.

. A motor 43 is mounted in the lower part of the frame and carries abelt 42 extending upwardly to the pulley all on the drive shaft of the Worm. The motor is provided with two pulleys 62 and 63 on its shaft to provide for different speeds of operation. In order to keep the belt 6l always taut it is arranged so that the weight of the motor is supported by the belt. rlhe base of the motor is provided with a beveled insulating block 64 which will slide in the vertical dovetailed guide 65.

j In Fig. 2 is shown a preferred form of device for heating the shoe l. A gas controlling valve 66, is shownV at one end of the machine leading to a mixer 67 from which the pipe 68 leads to about the middle of the As the roll ap-l length of the shoe. From the pipe 68 exv tends in each direction a burner 69. The two burners 69 cover substantially the ,Whole the shoe and since'tlie fuel is'led length of into the center of the device a. substantially uniform heat throughout the length of the shoe in Contact, and means adjacent the roll to release the grasping means.

3. ln an ironing machine, a heated shoe, a toggle to force the roll and shoe into resilient contact, a toggle latch, a feedin board, and means controlled by the feeding board to actuate said toggle latch.

Ll. ln an ironing machine, a roll, a shoe, means to force the roll and shoe into resilient contact including a pin, a hook to hold the pin, and pivoted spring supported means adjacentY the roll to release the hook.
